QCan I use the 102C Rigid Colony Muskrat Size Live Trap
to catch flying squirrels?

AThe 102C Rigid Colony Muskrat Size Live Trap is only meant to trap Muskrats or similar sized animals. While it might work for flying squirrels, we cannot guarantee it. We recommend looking at the E35 Excluder with One Way Door trap. Excluders are designed to let animals remove themselves from unwanted areas. Excluders have mounting wings which allow them to be attached directly over the animals' entry/exit hole. The one way door lets animals exit but prevents them from returning.
